Gurn-Enf Application le February 18, 1925. Serial No. 10,064.

An important object of the invention is to.V

provide a machine of this character which 1Q will'automatically return the cloth passing through-the machine, to its normal path of travel should the cloth for some reason be fedl laterally with respect to the machine into which the cloth is passing. I

-A still further object of the invention is to provide means whereby the feeding rolls of the machine may be adjusted to operate' in vertical spaced relation with each other or in horizontal 'spaced relation with each other as shown by Figure-a5 of the drawings. With the foregoing and other objects in lview which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafterl described and claimed, it being'understood that changes Vin the precise embodiment `of the invent-ion herein disclosed, maybe made within the sco e of what is claimed, without departing rom the spirit of the invention.

Referring to the drawings: Figure 1 is a front elevational view of 'a device constructed in accordance with th inyention. i

Figure 2 is an enlarged detail view partly broken away illustrating the means for adjusting the roll bearings taken on line 2-2 of Figure 4.

Figure 3 is a plan view of the device. f Figure 4 is a side elevational view of one of the roll supporting bearings.

Figurev 5 is a sectional view taken lon line 5--5 of Figure 1.

Figure v6is an elevational view illustrating one of the switch members. A

Figure 7 is a sectional view through one of the switch members. l

Figure 48 is a diagrammatic v'iew illus- 66 bythe bases 6, in a manner to permit the trating the circuits for controlling .the

device .to bereadily positioned before a cloth feeding machine. Mounted on the upper ends of the standards 5 are ,bearing members'7 which are circular in formation and provided with sockets 8 adapted to it over the standards 5 1n a manner as shown by Figure 5 of the drawings.

Positioned within the circular bear-ings 7 are adjustable supporting members 9 pro.-`

.vided with bearings 10 in which the shafts 11 and 12 respectively are '-positioned.

AMounted for rotation on the shafts 11 and 12 are gulding rolls 14 and 13 respectively, ,which are dlsposed at one side of the machine and guiding rolls 16 and 15 respec tlvely disposed at the iopposite side of the machine, the guiding rolls 13 and 14 being provided with spirally formed grooves de. fining ribs while the rolls 15 and '16 are provided with spirally formed grooves de. tfinlng rlbsy disposed in the opposite direcion.

ISecured to the rolls 13 and 14 are brake drums 17 that are engaged by the brake bands 18, the brake bands being anchored to the supporting members 9, at 19,`the opp'oslte ends thereof being secured to the connecting member 20, which in turn is carried on the inner end of the shaft 21 lthat extends through the supporting member 9 associated therewith.

Mounted on the outer end of the shaft 21 are ratchet wheels 22 that are engaged by the pawls'23 supported on the vertical arm'90 24, the pawls being held into engagement `with lthe ratchet wheels 22 by means of coiled spring 25.

The arm 24 is secured to the arm 26 that extends at right angles with respect thereto, 95 which arm 26 has pivotal connection with the rod 27 which in turn has pivotal connection with the core 28 Yof the Asolenoid 29. a The reference character 30 indicates a coiled spring that is also mounted on the shaft 21 100 and engages one of the ratchet wheels for returning the ratchet wheels to their normal 'positions after they have been actuated by 35, the ratchet wheels being controlled by the movement of the arm 36 that is operated by the solenoid 37 in a manner as is the arm 26 and ratchet wheels 22 previously described.

The arms 38 are bolted to the supporting members 9 to move therewith, it being understood that two of these supporting members are provided, one at each end of the machine. Rods 39 connect the arms 38 and lic in spaced relation with the rolls to support the cloth as it passes to and from the rolls. n

Positioned under the rolls 14 and 16 is a rod 40 that acts as a support for the arms 41 that extend downwardly and forwardly, as shown by Figure 5 of the drawings. At the forward ends of the arms 41 are Contact members 42, each of which being provided with a central insulated section 43 against which the contact members 44 normally lie, the contact members 44 being carried by the arms 45 that in turn are secured to the rods 46.

The arms 41 are hollow to accommodate the inner ends of the insulated rods 46, which carry disks 47 the disks being formed with openings to accommodate the coiled springs 48, the opposite ends of the coiled springs being anchored to the arms 41'at 49, the coiled springs being constructed in such a manner as to urge the arms 45 inwardly when the springs have been placed under tenson by the lateral or outward movement of the cloth.

Thus it will be seen that when the arms 45 54 that communicate with openings in which l the pins 55 are positioned, the pins 55 being provided with tapered extremities adapted to bite into the circular bearing 7 to hold the supports 9 in their positions of adjustment.

' The pins 55 F ig. 2 are moved by their contact with the tapered surfaces 56 of the members 57 that are formed with threaded extensions 58 disposed' in the threaded openings 59 of the supports.V Thus it will be seen that as the members 57 are moved inwardly pressure is brought to bear on the pins 55 to cause them to move into engagement with their bearings. l

The operation of the device is as follows: `Assuming that cloth 60 is being fed through the machine in a manner as shown by Fig. 3 of the drawings. It is obvious that the arms 45v are held in their vertical positions by their contact with the edges of the cloth which in the present showing is indicated by thc reference character 60. Should the cloth for some reason move 'laterally to the left, the arm 45 at the right hand side of the roll 14 will follow the lateral movement of the cloth, due to the action of the coiled spring 48, to the end that a circuit will be completed between the contact members 42 and 44 associated with the arm which has moved.

The solenoid 29 at the right hand side of the machine is operated to the end that the arm 26 is moved downwardly causing the pawl to move the ratchet wheels 22 and shaft on which they are mounted. With the movem'ent of the shaft, the brake bands 18 are moved to their active positions to grip the drums associated therewith to the end that the rolls 13 and 14 are prevented from rotating. It follows that as the cloth continues to move over the rolls, the ribs formed btween the spirally formed grooves will act to feed the cloth to the right of the machine, where it will take a straight path of travel.

In the event that the cloth 60 should move to the right hand side of the machine, the arm and contact member at the opposite side of the machine will operate in a manner as previously described.

l. A cloth guiding machine including a support, shafts mounted on the support, rolls mounted on the shafts and having spirally formed grooves with whichl cloth contacts to rotate the rolls when the cloth passes through the machine, braking means at the ends of the rolls for stopping the rolls, pivoted upstanding fingers supported at opposite edges of the cloth passing through the machineand adapted to be engaged by cloth moving laterally over the rolls, contact mem bers carried by the fingers and adapted to completey a circuit for operating lthe braking mechanism, when the fingers are moved laterally by the action of the cloth, and means for normally returning the armsV to their normal positions.

2. A' cloth guiding machine including a support, a pal-ir of shafts mounted on the support, rolls mounted on the shafts and having grooves formed therein, brake drums at the ends of the shafts, brake bands associated with the drums andadapted to grip the drums to stop rotation ofthe rolls, shafts for operating the brake bands, ratchet wheels on the shafts, pawlsfor moving the ratchet wheels, electrically controlledmeans for operatingthe pawls, and means controlled by the lateral movement of cloth passing through the machine for operating the electrical meansv to stop the rotation'of rolls.

In testimony that I claim the foregoing as my own, I have hereto affixed my signature.

ROBERT DANIEL TACKABERRY.
